Hi,

I have a CCME with 10 ip phones but I have a problem when these phones start a call. Some times the user dial a number to the PSTN but the call cannot complete, the phone indicates that the call has been established but isn't so, and the user remains waiting a long time and the call doesnt start. This happens randomly and began with this behavior two or three weeks ago. Does anybody know what is the reason of this?

Thanks
